I dont have a need at this time unfortunately, and I should have been more specific: Delta/Rockwell/General gear will always get a premium over king/canwood/craftex/etc. You only need to look at the auction and see what the Canwood Sander went for compared to the Rockwell/Delta, about half the price IIRC. So based on my experience, I'd guess your sander is likely worth closer to 400-500.
